Donkwa Enriched With Goron‐Tula (Azanza garckeana) Modulates Sexual Behavior and Activity of Enzymes Linked With Erectile Dysfunction in High‐Fat Diets/ Streptozotocin‐Induced (STZ/HFD) Diabetic Rats

open access: yesFood Chemistry International, EarlyView.
(A) Mount number, (B) mount latency, (C) intromission number, and (D) intromission latency are the parameters of sexual behavior. Met = metformin. D100 = 100 Donkwa. D90G10 = 90% Donkwa + 10% Goron‐Tula. D85G15 = 85% Donkwa + 15% Goron‐Tula. D80G20 = 80% Donkwa + 20% Goron‐Tula. The mean ± standard error of the mean (SEM) expressed the results. *Values

Optimising the Eco‐Friendly Extraction of Carotenoids From Gac Fruit: A Sustainable Solution for Natural Red Food Colourants

open access: yesFood Chemistry International, EarlyView.
Gac fruit's high carotenoid content, especially in the aril, makes it an excellent natural red pigment source for food applications, offering a safer alternative to synthetic dyes. Ethanol extraction achieved the highest overall pigment recovery (89.53%), whereas ethyl lactate extraction yielded the highest levels of total carotenoids, β‐carotene ...

Strategies for Identification and Mitigation of Sanguinarine in Mustard Oil Adulterated by Argemone—A Comprehensive Review

open access: yesFood Chemistry International, EarlyView.
Sanguinarine, a toxic alkaloid present in argemone, can lead to epidemic dropsy or chronic diseases through DNA intercalation and immune system suppression. Regulatory efforts face challenges due to economic motivations for adulteration as well as technical, social, and infrastructure barriers.

Dietary and biomarker‐guided strategies as supportive measures in the fragile X syndrome

open access: yesFood Biomacromolecules, EarlyView.
Abstract The fragile X syndrome (FXS) is an inherited neurodevelopmental disorder that primarily affects males, often resulting in an IQ below 55, while about two‐thirds of females also experience intellectual disability. Physical features may include an elongated face, prominent ears, finger joint laxity, and enlarged testes in males.
